Search of Hydrogenase / Nitrogenase

 
Hydrogenase is the very superior biocatalyst to perform for hydrogen generation and fuel cells.
 
However, the highly active hydrogenase has the problem of deactivating after exposure oxygens and the Oxygen stabled hydrogenase has a disadvantages of low hydrogen activity.
 
With this research, we search the new hydrogenase which have "high hydrogen activity and Oxygen stability" and analyze them with own developed methodology.
 

 
              
 

Recent achievements

From Aso Spring (in Kyushu) Our laboratory has succeeded to isolate the new filamentous Thermophilic cyanobacterium, "Citrobacter sp. strain S-77(AB668058)" and and find the new "Hybrid type Hydrogenase " which has the high hydrogen activity and Oxygen stability.
And we found the [NiFe(Se)] hydrogenase which has new iron-sulfur cluster from the sulfate-reducing bacterium.
